Higher prefixes were not redefined by JEDEC.In order to avoid this inconsistency, the International Electrotechnical Commission (IEC) has proposed the binary prefix which uses kibi [Ki], mebi [Mi], and gibi [Gi] for 1024¹, 1024², and 1024³ respectively.The following table from Wikipedia gives an overview.up vote 4 down vote kH/s means thousands of hashes per second.MH/s means millions of hashes per second.GH/s means billions of hashes per second.300 kH/s is 300,000 hashes per second or .3 MH/s.up vote 2 down vote Hello I would refer you to wikipedia Metric prefixes.Hashes are measured in standart SI metric prefixes such as Kilo - 1 000 Hashes/s Mega - 1 000 000 Hashes/s Giga - 1 000 000 000 Hashes/s E.G.2 Kh/s means that 2 000 hashes can be solved per second.If you would like to know more about Hash visit bitcoin.it From bitcoin.it : A hash algorithm turns an arbitrarily-large amount of data into a fixed-length hash.The same hash will always result from the same data, but modifying the data by even one bit will completely change the hash.

Like all computer data, hashes are large numbers, and are usually written as hexadecimal.BitCoin uses the SHA-256 hash algorithm to generate verifiably "random" numbers in a way that requires a predictable amount of CPU effort.Generating a SHA-256 hash with a value less than the current target solves a block and wins you some coins.Or you might check this: Cryptographic hash protected by Tim Post Thank you for your interest in this question.Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).Would you like to answer one of these unanswered questions instead?Browse other questions tagged hashpower terminology or ask your own question.At first, miners used their central processing unit (CPU) to mine, but soon this wasn't fast enough and it bogged down the system resources of the host computer.Miners quickly moved on to using the graphical processing unit (GPU) in computer graphics cards because they were able to hash data 50 to 100 times faster and consumed much less power per unit of work.

During the winter of 2011, a new industry sprang up with custom equipment that pushed the performance standards even higher.The first wave of these specialty bitcoin mining devices were easy to use Bitcoin miners were based on field-programmable gate array (FPGA) processors and attached to computers using a convenient USB connection.FPGA miners used much less power than CPU's or GPU's and made concentrated mining farms possible for the first time.Application-specific integrated circuit (ASIC) miners have taken over completely.These ASIC machines mine at unprecedented speeds while consuming much less power than FPGA or GPU mining rigs.Several reputable companies have established themselves with excellent products.Currently, based on (1) price per hash and (2) electrical efficiency the best Bitcoin miner options are: AntMiner S7 4.73 Th/s 0.25 W/Gh 8.8 pounds $479.95 0.1645 AntMiner S9 13.5 Th/s 0.098 W/Gh 8.1 pounds $1,987.95 0.3603 Avalon6 3.5 Th/s 0.29 W/Gh 9.5 pounds $499.95 0.1232 For a comprehensive comparison of bitcoin mining hardware.

Two major factors go into determining the best bitcoin mining hardware: (1) cost and (2) electricity efficiency.Bitcoin mining is difficult to do profitably but if you try then this Bitcoin miner is probably a good shot.Application-specific integrated circuit chips (ASICs) are bitcoin mining hardware created solely to solve Bitcoin blocks.They have only minimal requirements for other normal computer applications.Consequently, ASIC Bitcoin mining systems can solve Bitcoin blocks much quicker and use less less electricity or power than older bitcoin mining hardware like CPUs, GPUs or FPGAs.As Bitcoin mining increases in popularity and the Bitcoin price rises so does the value of ASIC Bitcoin mining hardware.As more Bitcoin mining hardware is deployed to secure the Bitcoin network the Bitcoin difficulty rises.This makes it impossible to profitably compete without a Bitcoin ASIC system.Furthermore, Bitcoin ASIC technology keeps getting faster, more efficient and more productive so it keeps pushing the limits of what makes the best Bitcoin mining hardware.
